FILLING-REPLENISHING LOOM;

SPECIFICATION forming part of Letters Patent No'. 685,236, dated oetober 22, 190i. Application ined August 3,1901. Seraing. 70,762. (No model.)

To LZZ whom, t may concern:

Be it known that I, WILLIAM HAYNES, a citizen of the United States, and a resident of Atlanta, county of Fulton, State of Georgia, have invented an Improvement in Automatic Filling-Replenishin g Looms, of which the following deseription, in connection with the accompanying drawings, is a specification, like Characters on the drawings representing like parts. p

This invention relates more particularly to so-called feeler looms, provided with mechanism to automatically replenish the filling when the supply of the latter in the Shuttle has been exhausted to a predetermined extent.

In my present invention I have provided a feeler to intermittinglyl cooperate with the iillin g in the shuttle and tobe moved thereby until the desired exhaustion of the filling has been effected, and at such time the practical cessation of filling-induced movement of the feeler permits the operative positioning of a device to transmit the movement of the shuttle -body to effect the actuation of means which control the time of operation of the lling-replenishing mechanism.

Figure l is a top Or plan view, centrally broken out, of a loom provided with automatic filling replenishing mechanism and with one embodiment of my invention applied thereto. Fig. 2 is a transverse sectional detail on the line a; no, Fig. l, looking toward the right. Fig. 3 is an enlarged sectional detail taken longitudinally of the feeler to show more clearly the structure thereof and of certain devices mounted thereon, and Fig. 4 is a detail in side elevation of `a portion of the controlling means for the filling-replenishing mechanism on the line m' x',-Fig. 1.

In Fig. 1 the lay A3, breast-beam A40, shipper SX and its notched holding-plate H, the filling-feeder F to receive filling-carriers b,

the transferrer f', and the operating or controlling rock-shaft d' to effect a change of filling when the rock-shaft is rotated in the direction of the arrow 20, Fig. l, may be and are all of usual construction and Substantially as shown in United States Patent No. 646,866, dated April 3, 1900, and in the-structure shown the self-threading Shuttle S is provided with a fresli supply of filling when in the shuttle-box adjacent the feeder F upon actuation of the illing-replenishing mechanism. y p

The front wall B2 of the shuttle-box BX (see Figs. l and 2) is provided with a 'slot 3,herein shown as cut down from the top of the Wall, to register with an aperture or slot 4 in the side Wall of the Shuttle when the latter is in the box BX, the Slot'4 being located opposite a portion of the barrel of the filling-carrier near the base or head thereof.

On the outer end of the holding-plate H, I have herein shown a box-like support or stand ax, somewhat Similar to a loom-temple stand and having a longitudinal chamber d to receive a spiral spring S5, which is herein shown as coiled around the reduced end d of the shank a of the feeler. The shank and its reduced end are mounted to slide in the stand ctx, substantiall y at right angles to the breastbeam, the stand being adj ustably secured, as by set-Screws 5, Fig. l, to a supporting-plate 6, fastened to the holding-plate H in any suitable manner. The outer end of the Spring 35 bears against the outer end wall of the stand ctx, and its inner end bears against the shoulders-8 ofthe feeler-shank.

Thefeeler is herein shown asa thin iat plate a3, connected by 'a bend at with the shank d2, the bend serving to offset the feeler and position it opposite slot 3 in the front wall of the shuttle-box, hereinbefore referred to. i The feeler is yieldingly sustained by the means described in position to enter the slot 3 at each forward beat of the lay, and at each :alternate-beat when the shuttle is in the shut- 'tle-box' I3 the feeler will also pass through the slot 4 in the shuttle-Wall to engage the filling on the filling-carrier, Such engagement Operating to move the feeler Outward as the lay completesv its beat up until the filling has been exhausted to a predetermined extent, and atsuch time ,the filling-induced movement of the feeler will cease, as there will be an insufficient amount of filling on the barrel of the filling-carrier to eect it.

The feeler moves in a rectilinear path, as will be manifest, transverse to the breastybeam and substantially at lright angles to the lay.

roo

The feeler is shown in Fig. 1 as made quite broad, so as to contact with a considerable portion of the lling, to thus distribute over the latter any strain due to impact and to thus lessen the chance of rubbing or breaking the filling. I have herein shown a 1-shaped block a5, mounted on the feeler and adjustably secured thereto by set-screws 10, the shanks of which pass through longitudinal slots 12 (see Fig. 1) in the sides ofthe block and clamp the latter in position on the feeler, a stop-screw 13, screwed into the bend a4, serving as a back-stop for the block. The inner separated ends of the block a5 support a transverse pin a6, serving as a fulcrum for an actuator cx, said actuator extending longitudinally of the block and between its separated sides, as clearly shown in Figs. 1 and 3, and having its outer end bent to form a depending toe c, which passes through an aperture or hole as iu the feeler a2, the rear end of the actuator being bent up and extended rearwardly beyond the adjacent ends of the block a5 to form a pin c', the actuator being herein shown as normally maintained in inoperative position by a suitable spring 38. The actuator is thus movable with and also relatively to the feeler, and, as will appear hereinafter, the actuator serves to transmit to the controlling means for the filling-replenishing mechanism the movement of the shuttle-body when a change of filling is to be effected. The rock-shaft d' has an upturned arm d5, Fig. 1, the upper end of which is in the path of movement of a slide-bar d, locatedadjacentthe standmxjn which is mount; ed and longitudinally movable the usual slide m, on which the weft-fork 'm/ is pivoted, the slide-bar having pivoted upon it at d7 (see Fig. 4) a latch-carrier d3, rearwardly extended and at its end being pivotally connected with a depending latch d, said latch overhanging the inner end of the slide-bard@ When the latch is in the position shown in Fig. 4, a shoulder w on the usual weft-hammer W, Fig. 1, passes below the end of the latch; but if the latch is permitted to drop into the path of the shoulder w the forward movement of the wefthammer will move the slide-bar outwardly and the upturned arm d5 will be swung out, rocking the shaft d in the direction of the arrow 20, Fig. 1, and in well-known manner eecting the actuation of the filling-replenishing mechanism. A laterally-extended shoulder d10 on the side of the latch-carrier (see Fig. 4 and also Fig. 1) is beveled on its under face, as at 15, to rest lupon the correspondingly-beveled face of the inner end of a detent dw, fulcrumed on a vertical pivot at d1 and normally held by a suitable spring 815 (see Fig. 1) in the position shown in said figure, the end of the detent beneath the shoulder d10 being held by the spring against a fixed upturned stop 40. At the opposite side of its fulcrum the detent is extended, as at d, beneath the feeler a3, and normally the toe c ofthe actuator on the feeler is held above the path of the detent by the spring .98. So long as the detent remains in normal position herein shown the latch d" will be maintained by it in inoperative position.

As has been before stated, the feeler a3 will be moved by engagement with the filling in the shuttle on every other pick from its normal or neutral position toward the front of the loom against the action of the spring s, and such filling-induced movement of the feeler will be effected before the finger c of the actuator can come in contact with the side wall of the shuttlebody. As the filling weaves off, however, the distance between the finger and the side wall of the shuttle gradually decreases until the filling has been exhausted to a predetermined extent, and at such time the diminution of the diameter of the mass of filling on the filling-carrier will be sufficient to permit the finger c' to engage the side wall of the shuttle, and as the shuttle is moved forward by the lay it will first act to tip the actuator cX on its fulcrum to depress the toe c into the path of the detent, and at such time the side wall of the shuttle will bear against the ends of the block a5 and will impart longitudinal movement to the feeler in the direction of the arrow 35, Fig. l, bringing the toe c against the extended part d15 of the detent and swinging the latter on its fulcrum to withdraw its inner end from beneath the shoulder d10. The latch-carrier da thereupon drops to permit the latch d to move into the path of the shoulder w on the wefthammer, and the latter will on its next forward movement Yengage the latch and through the devices described will effect the actuation of-the filling-replenishing mechanism. After the filling has been changed the various parts will return automatically to nor; mal position, the spring S15 moving the detent to normal position, the inner end acting upon the beveled face 15 of the shoulder d10 to lift the latch-carrier and restore the latch to normal inoperative position.

The movement of the feeler from neutral position when effected by or through the actuator c, as hasbeen described, is practically independent of the filling remaining on the filling-carrier, because the movement of the shuttlebody is transmitted to the feeler, not through the filling-carrier, as heretofore, but through the actuator to the supporting-block a5, rigidly mounted on the feeler.

The outer end of the part a of the feelershank is bent up, as at 55, outside of the end of the box-like stand ctx to limit the movement of the feeler rearwardly.

The mechanism herein shown is exceedingly simple, effective, and rapid in its operation.

The adjustment of the actuator on the feeler is effected by means of the set-screws 12, and the feeler as a whole is adjusted on the holdin g-plate 1I by or through the clamp-screws 5.

The latch mechanism is not herein claimed, as the same is not, broadly, of my invention.
